    Abstract

    Ruhemann's Purple (RP), the reaction product of ninhydrin with amino acids, forms coordination compounds with many metals. However, only a few of them fluoresce. A model for the structural and photophysical features that underlie the formation of fluorescent metal-RP compounds has been developed to establish guidelines for the design of optimized ninhydrin analogs and metal-RP complexes. The application of such complexes to the detection of latent fingerprints, a special surface analytical chemistry problem, is discussed.
